SPECIFICATION forming part of Letters Siatent No. 319,733, dated June 9, 1885.

Application led November 11, 1894. (No model.)

To all whom it may concern,.-

Be it known that I, JAMEs S. MCMURTRY, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful 5 Improvement in Dnmping-XVagons, et' which A the following is a full',V clear, and exact description, reference being had to the accompanying drawings, forming part ef this specification.

1o Figure l. is a side View with the body in discharging position. Fig. 2 is a top view with half of the body omitted. Fig. fi is a longitudinal section, parts beiuf,r shown in side View. Eig. *i is a detail transverse section at 4 4, Fig. 3.

The fore wheels are shown at A, and-the hind wheels at B. v

'C is the fore axle, and D the hind axle.

E F .is a bolster resting on the fore axle and 2o connected with it by the lcingbolt G, as usual, allowing the axle to turn beneath the bolster.

H is a reach connecting the bolster E with the hind axle, and the bolster I thereon. This connection may be made by a couplingpole, or in any other suitable manner.

J is a frame supported on the holsters and inclining downward from the front to the hind end. This frame has side standards, K, forming side guides te the body L. The body has along its bottom rails M, (see Fig. 4,) which run in the cireumferential grooves of the wheels N, upon which the body is directly supported, the wheels turning on arbors fixed inthe bars of theframeJ. Six of these wheels are shown, (three for each rail,) but I do not eonliue myself to the use of any special number.

O is a cleat attached to the under side or bottoni of the body and bearing against the 4o front side 0l' the bolster I to prevent the frame sliding backward. The frame may be secured to the bolste '51 F and l in any suit` ableI manner. 'l'here are u pmu-ucd hooks l?, secured to the cle-.it to arrest the backward Ar, movement ol' the body along the frame, the hooks engaging n. cross-bar, Qf, .secured to a projection, Q, at the bottom of the body. The hooks and bar ferm theI binne on which the ends to the body.

the body tilts backward when dumping its load. t

It R are plates having a space, R', between each pair, through which the cross-bar is inserted. The crossbar slides under the plates, and the latter prevents the tilting ofthe body before it reaches the proper position.

To prevent the body tilting over too far, there are arms S, pivoted at s to the sides of the frame J, and extending between the sides of the body and strips or cleats T, fastened at The arms have at the 6o free ends heads S, too large te pass through the slot` between the body and cleat T, the upper edge of the body coming in contact with the-head when they body has tilted baci; to a certain degree.

To give means for drawing the body for ward on the frame into its loading position, a chain or cord, U, is attached to the bottom of the body and carried around a windlass, V, at the front of the frame. The windlass may 7o be turned by a hand-crank, W, either upon the windlass-shaft or connected therewith by cog-gearing.

X is a cog-v. heel upon the windlass, and Y is a dog, which may be turned either into or out of engagement with the cogs of the wheel, so as to prevent the rotation of the wllass. This dofJ is more especially used when the body if, drawn up toits loading position to hold it in such position by preventing the 8o uneoiliug of the rope or chain U from the windlass.

It will be seen that the rails M and the grooved wheels on which they work form very eleetive guides to the body in running upon the fralne,and that the standards K serve to guide the body when being tilted, and to prevent the rails being thrownr ont of the wheel-grooves by violent jars, die.

The upper portion, F, of the fore bolster 9o may be attached tothe lower portion, E, or :i1-.xy 'ne attached to the lrnnic J. In the latter case the frame may be ,ist upon the ordinary rnuninggears of a wagon, and will have the necessaryinclination, as the bolster E sets upon the front bolster of the saine.

I claiml with the running-gear and supporting-frame, 1. In a dumping-wagon, the combination, of the body haw-iing cleats oi strips T, mid the with the running geur, of a body or box pioarmSS,pivoted to the frmne,extendi.ng between `vided with rails Minid projection Q, carrying the cleats and the body, and provided' with acrossbar, Q', anddthefmme J,huvinggrooved heads S' at their free ends. rollers y, upturne hooks P, and guard-plates l, y f y R, leaving openings R between them, and JAMLS b' MOMUR un" means for retaining the body or box in nornml XVitnesSes: condition.
